Effects of Oxytetracycline on Population Growth and Genetic Diversity of Euplotesvannus (Marine Protist) [PDF]
抗生素作为一类环境污染物在海岸带生境中广泛存在,它们对海洋原生生物遗传多样性的影响还不清楚.本工作以一种海洋纤毛虫原生生物(扇形游仆虫(Euplotes vannus))为例,研究了一种常见四环类抗生素(土霉素)对其生长的影响,并通过单细胞(个体)分析,探索了抗生素对其大核基因组中核糖体小亚基RNA基因(SSU r DNA)序列多样性的影响.结果表明,与对照组相比,3个土霉素处理组(1,10和20μg/m L)中纤毛虫的自然增长率随土霉素浓度升高显著降低,细胞大小则呈增大趋势.SSU r ...

Screening and Characteristics of Bacteria and Enzyme for Degradation of Malachite Green from Marine Sediment [PDF]
孔雀石绿是一种三苯基甲烷类染料,广泛应用于水产、纺织、造纸等产业,导致水生环境化学需氧量(COD)和生物需氧量(BOD)大幅提高,阻挡光的透射,严重影响水生生物的生长,同时其毒性和致癌性也会通过食物链传递给人类及其他陆生生物。本研究以深海和红树林沉积物中微生物为研究对象,采用富集培养和宏基因组技术对可降解孔雀石绿的微生物及功能基因资源进行挖掘,并对其降解途径及代谢产物进行研究,为近海环境修复提供潜在的、可应用的生物资源 ...
